Captain Silas Alberec

The Hellslayer is a massive barbed and sigil-etched power mace that is a deadly bane to the witch and the daemon. The Hellslayer counts as a Master-crafted Thunder Hammer, but requires two hands to use (Alberec cannot claim an extra attack from having a pistol). In addition to the Thunder Hammer abilitys (Strikes Last; Shaken Results on hit vehicles; Prevents attacks by models wounded), it also has the following; Against targets which are either daemons or that know psychic powers of any kind, all successful to hit rolls wound automatically.

Whenever Alberec is targeted by a psychic power, including any squad he is joined, or vehicle he is mounted in, roll a D6. On a 4+ the power is nullified and nothing happens.

Individual model. Can join other units in battle

The iron halo grants a 4+ invulnerable save.

If the template used by teleporting Terminators making a Deep Strike is centered  on the model with the homer, then it does not scatter.

When a unit including a model wearing Purity Seals falls back, roll one extra D6 for the fall back distance, and then pick the D6 results you want.
